Main research direction for water pollution control engineering, industrial water conservation technology and environmental biotechnology, in the use of biological wastewater treatment technology and equipment research and development and engineering application of in-depth research, over the years is committed to the reuse of wastewater and low-cost treatment technology development, presided over the undertaking of a number of large-scale domestic provinces and municipalities of industrial wastewater treatment projects, especially good at the treatment of high-concentration organic wastewater treatment technology. He is especially good at the treatment of high concentration organic wastewater. He has undertaken 32 projects, including national key scientific and technological research, national high-tech project (863) sub-themes, national and provincial natural science funds, provincial key, provincial science and technology development funds, as well as enterprise-commissioned scientific research and scientific and technological service projects, etc., and has published more than 50 papers in domestic and foreign academic journals and international conferences, and 2 monographs.
